[1]我们报告的第一个连续测量的硝酸氯（ClONO 2）在高纬度地区采取的改进临边大气光谱仪（ILAS）上的先进地球观测卫星（ADEOS）和处理使用最新的数据检索算法（版本6.1）。性能的测量，验证与三个球载传感器，ClONO 2在北极和南极平流层的季节性变化，以及版本6.1的算法和数据特性的北极和南极的简要说明。虽然ILAS测量的ClONO 2数据显示，平均值比验证数据低30%，但它们与验证数据一致，在15至32公里高度ClONO 2测量的总误差（20%-40%）范围内。在北极，1997年春季，在极涡内部出现极地平流层云（PSC）后，观测到ClONO 2含量的增加。这是1997年北极春季ClOx激活后，ClONO 2形成而不是HCl的偏好的结果。在南极，ClONO 2量显示出强烈的当地时间/纬度的依赖性在1997年的秋分。
[1] We report the first continuous measurements of chlorine nitrate (ClONO2) in high-latitude regions taken by the Improved Limb Atmospheric Spectrometer (ILAS) on board the Advanced Earth Observing Satellite (ADEOS) and processed using the latest data retrieval algorithm (version 6.1). Performance of the measurements, validation with three balloon-borne sensors, and seasonal variation of ClONO2 in the Arctic and Antarctic stratosphere are presented, as well as a brief description of the version 6.1 algorithm and data characteristics for both the Arctic and Antarctic. Although the ILAS-measured ClONO2 data show, on average, ∼30% lower values than the validation data, they agree with validation data within the combined total error (∼20–40%) of the ClONO2 measurements at ∼15- to 32-km altitudes. In the Arctic, enhancement of ClONO2 amounts was observed in spring 1997 after the appearance of polar stratospheric clouds (PSCs) inside the polar vortex. This is the result of preference for ClONO2 formation rather than HCl after the activation of ClOx in this Arctic spring of 1997. In the Antarctic, ClONO2 amounts showed strong local time/latitudinal dependence around the austral fall equinox in 1997.
